  • UE User Equipment device
  • eNB enhanced or evolved Node B
  • LWA there is no additional IPSec tunneling between the UE and the eNB.
  • the overall architecture common for all three options is shown in Figure 1 .
  • the difference in the three options is whether the secondary cell is a WiFi Access Point (AP) (for LWA and LWIP) or a LTE eNB (for LAA) and whether an IPSec tunnel is established between the UE and the eNB via the secondary cell (for LWIP) or no such IPSec tunnel is needed (for LAA and LWA).
  • AP WiFi Access Point
  • LAA LTE eNB
  • the Radio Access Network (RAN) controls the usage of whether user data traffic goes via licensed or unlicensed spectrum. This can be done on a per bearer, per Internet Protocol (IP) flow, or per packet basis.
